BUTTON.

SPECIFICATION formingpart of Letters Patent No. 236,288, dated January 4., 1881.

Application filed November 29, 1880.

To all whom it may concern:

Be it known that I, LEO H. WISE, a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Buttons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of pantsbuttons which are made and sold in two parts, and which are joined together and attached to the garment in one and the same operation, the objects of such buttons being to provide for their ready attachment to the garment without the necessity of sewing them.

The improvement will first bedescribed, and the particular part to which the invention relates will then be designated in the claim.

In the drawings hereto annexed the figures are made on a large scale for the purpose of better illustration.

Figure 1 is a partly-sectional view of the button. through the line was in Fig. 1. Fig. 3 is a side view of the button without the shank-head. Fig. 4 is a plan view of the shank-head. Fig. 5 is a side view of the shank and its head.

The button proper, A,is made of two pieces of sheet metal, the outer part, a, and the inner part, b, which two parts are secured together by the rim 0/ of one part being crimped over and closed down on the rim of the other part, as shown in Fig. 1. That part c which metrically-opposite sides of the shank-socketthe metal is cut to form a tongue, (1, which remains connected at one part, while the free end is pressed inward. As seen in Fig.1,that part of the tongue which is connected to the socket Fig. 2 is a cross-section of the parts (No model.)

which is at a right angle to the length of the shank, and the other flat side of which is at an obtuse angle thereto, the right-angled side of the notch being nearest the sharp point of the shank. It will be seen that when the pointed end of the solid shank enters the shank-socket the two tongues d of the socket will engage with the two notches h onthe shank, while the point extends to and within a suitable recess formed by pressing out the center of the outer part, a, of the button, as shown at g.

To attach the button to a garment theflared mouth 0 of the button is placed on one side of the fabric or goods, and the sharp point of the solid shank is placed against the other side of the fabric and directly opposite the flared mouth. Force must now be applied against the shank-head sufficient to cause the point 9 to penetrate the fabric and enter to its position within the shank-socket, when the fabric will be tightly clasped or secured between the flared mouth and shank-head. By this arrangement the use of a tapering needle or stylus is obviated, as also is any mechanical contrivance to force the two parts of the button together and secure it to the fabric. As the notches h in the solid shank have each two flat sides, and one of the tongues 01 of the shank-socket bears inward against the obtuseangled flat side of each notch, the shank-head is thereby prevented from accidentally turning, and the button will remain securely attached; but if it bedesired to remov e the button the same can be readily effected by applying sufficient force to turn the shank-head onequarter around, thereby releasing the tongues from engagement with the notches. To facilitate this the shank-head may be six or eight sided, as shown in Fig. 4, instead of circular.

Having described'my invention, I claim and desire to secure byLetters Patent'of the United States Ametal button whose shank cformsasocket which the tongues will engage, as shown and which is provided at two diametrically-oppodescribed. 10 site sides with a, tongue, 01, one end of which is In testimony whereof I aflix my signature connected to the sides and the other end is in presence of two witnesses.
